Is an Idle Speed of 800 to 900 RPM Normal for the New Jetta?

[Luke]

An idle speed of 800 to 900 RPM is not normal for the new Jetta. The typical idle speed for the Volkswagen New Jetta is around 700-800 RPM. Introduction to Car Idle Speed: Car idle speed refers to a working condition. When the engine runs without load, it is called idling, meaning the car is in neutral gear. The engine speed during idling is referred to as the idle speed. The idle speed can be adjusted by modifying the throttle opening size, among other methods. Idling essentially means the engine is "running without doing work." Introduction to Car Idle State: When the engine is running, if the accelerator pedal is fully released, the engine enters the idle state. When adjusting the idle speed, the RPM should not fluctuate abruptly, as this can cause premature wear to the engine. It is best to have the idle speed adjusted at an automotive repair facility. When the car is parked and the engine is started, the minimum stable engine speed is called the parking idle speed (the process of transitioning from a cold engine idle state to the idle state at normal operating temperature is called warm-up or heating).
